Issue
Synonymy based on examination of numerous specimens including syntypes of Ancistrus dolichopterus; no recent redescription, but see Eigenmann and Eigenmann (1890:448, as Ancistrus temminckii) for a complementary description, and Römer (1990) and Holota (1990) (both references as Ancistrus cf. hoplogenys) for figures of living specimens and reproduction observations in aquarium; 12S and 16S mitochondrial rRNA gene sequences used in molecular phylogenies by Montoya-Burgos et al. (1997: fig. 4; 1998: figs. 3 & 6; EMBL/GenBank Y08276; Y08324).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01738 (0.00936 - 0.03225), b=3.06 (2.91 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
